Converting your grill from natural gas to propane is a task that many homeowners consider for various reasons, whether it’s due to the availability of fuel, cost considerations, or simply a preference for propane’s flavor profile. This comprehensive guide will walk you through the process step by step, ensuring that you can safely and effectively make the switch. We’ve gathered insights from top sources and experts in the field to provide you with the most accurate and detailed information.

How to Convert Your Grill from Natural Gas to Propane

Understanding the Basics

Before diving into the conversion process, it’s essential to understand the fundamental differences between natural gas and propane.

  • Natural Gas: A fossil fuel primarily composed of methane, natural gas is delivered to homes through underground pipelines. It’s often considered more convenient since it’s directly piped to your home, eliminating the need for refilling tanks.
  • Propane: A byproduct of natural gas processing and petroleum refining, propane is stored in tanks and needs to be refilled when depleted. It’s known for producing a hotter flame than natural gas, which can be preferable for grilling.

Safety First: Pre-Conversion Considerations

Before starting the conversion, ensure you’re well-prepared and understand the risks involved.

  1. Check Compatibility: Not all grills are designed to be converted between gas types. Consult your grill’s manufacturer or user manual to determine if your model is convertible.
  2. Gather Necessary Tools and Parts: Depending on your grill model, you may need specific conversion kits, which typically include new gas valves, hose lines, and orifices.
  3. Work in a Ventilated Area: Always work outdoors or in a well-ventilated space to prevent the accumulation of gas fumes.

Step-by-Step Conversion Guide

1. Turn Off the Gas Supply

Before starting any work, ensure that the gas supply is turned off. If you’re using natural gas, shut off the valve from the source. For propane grills, disconnect the propane tank.

2. Remove the Existing Gas Components

Using the appropriate tools, carefully remove the existing gas lines, valves, and orifices. Store these parts safely in case you decide to revert to natural gas in the future.

3. Install the Propane Components

Following the instructions provided in your conversion kit, install the new propane-specific parts. This will typically involve attaching new gas valves, connecting hose lines, and fitting new orifices.

4. Reconnect the Grill

Once the new components are in place, reconnect the grill to the propane tank. Ensure all connections are secure to prevent gas leaks.

5. Test for Leaks

Before firing up your grill, it’s crucial to test for any potential gas leaks. Apply a soapy water solution to all connections and open the propane valve slightly. If bubbles form, this indicates a leak. Tighten connections or replace faulty parts as necessary.

6. Light the Grill

With everything in place and no leaks detected, you’re ready to light your grill. Follow your grill’s lighting instructions, and enjoy your newly converted propane grill!

Benefits of Converting to Propane

  • Higher Heat Output: Propane often provides a hotter flame, which can be ideal for searing meats and achieving a perfect char.
  • Portability: Propane tanks are portable, allowing you to move your grill easily or take it on the go.
  • Cost-Effective: In some regions, propane can be more cost-effective than natural gas, especially if natural gas prices are high.

Common Mistakes to Avoid

  • Skipping the Leak Test: Never skip the leak test. This step ensures your safety and the safety of those around you.
  • Using Mismatched Parts: Always use parts designed for your specific grill model. Using incompatible components can lead to inefficiencies or safety hazards.
  • Forgetting to Check Compatibility: As mentioned, not all grills are designed for conversion. Always check before starting the process.


Converting your grill from natural gas to propane can offer several benefits, from increased heat output to potential cost savings. However, safety should always be the top priority. By following this detailed guide and ensuring you have the right tools and parts, you can enjoy the advantages of propane grilling with confidence.
